Smart charge controller - Build your own charging station

As the heart of every intelligent charging station, the charge controller communicates with the vehicle and the connected backend, monitors the internal hardware of the charging system, the user interfaces as well as the charging socket and the charging cable.

The integrated PLC communication in accordance with ISO15118 for implementation of plug & charge, bi-directional communication with the vehicle as well as intelligent connection to energy management systems (EMS) are further innovative components of the charge controller.

A specially developed dynamic load management (eDLM software) integrated in the controller enables load management with up to 250 charging points within a local eDLM system, whereby the entire available energy is distributed in a highly dynamic and effective way using different profiles.

The charge controller is compatible with OCPP 1.5 and OCPP 1.6. Integration tests with different backend implementations of providers such as Vattenfall, Bosch, NTT and DRIIVZ have been successfully carried out, interoperability with common roaming platforms such as Plugsurfing and Hubject has also been ensured.

The charge controller supports 2.5G Edge and 4G UMTS mobile networks; a SIM card is required. Online service to identify errors is just as possible as local administration on site via USB interfaces, whereby updates and configuration settings can also be imported and duplicated via a service USB stick.

The technical basis for billing options in compliance with German calibration law is created by combining the CC612 charge controller with an EMH meter and transparency software.

The innovative technology results in maximum availability and safety for both the charging system and the vehicle to be charged. Since the controller does not only react to critical DC fault currents but also to small residual currents, which indicate deterioration at an early stage, it reports and deliberately terminates the charging process before the RCD is tripped.

User interaction is facilitated by RFID modules available as accessories, which include an RFID card reader and LEDs. In offline operation, the charge controller can either allow charging without authorisation or it can authorise users based on RFID and a local "white list".

The software for controlling all processes of the charge controller can be updated. This makes the CC612 future-proof. Updates (typically quarterly) can be easily installed via USB, Ethernet or over-the-air (OTA). If a vulnerability is detected in the software, it can be reported here.
